There are thousands of indoor ice rink arenas in the United States, Canada, and Europe. The combustion byproducts from the feel-powered ice resurfacing equipment are a potential health risk to both athletes and spectators. A field survey of ten ice rink arenas in Greater Boston and Halifax, Nova Scotia, indicates that the fuel type used by the resurfacer as well as the air exchange rate, the air distribution method, and the operation strategy of the ventilation system are significant contributing factors to the indoor air quality (JAQ) .
An integrated approach to energy management and auditing over the past 10 years has turned Australia's Parliament House into an energy champion. Total energy consumption and associated greenhouse gas emissions over that time have been culled by an impressive 52.3% and 41.2% respectively. Equally impressive is the fact that all energy efficiency improvements have been fully funded from energy savings.
This paper presents an original air conditioning concept and design development elaborated for a large arena, designed to accommodate the indoor sporting events during the 2000 Olympic Games in Sydney, Australia. An air conditioning system, which provides a great level of flexibility and economical operation, has been developed and its performance studied in detail by the use of our computational fluid dynamics (CFD) software.
The study reported in this paper is concentrated on the estimation of the heat transfer from air to ice due to convection. Together with measurements of temperature and moisture profiles, air movements have been visualised in a small-scale model of a planned indoor ice rink. Some field tests concerning moisture content and temperature also have been realized in two different ice rinks. The study indicates that a low emissivity layer in the ceiling decreases the risk for ceiling condensation, decreases the heat radiation on the ice and decreases the driving force for air mixing.
